PHA (Polyhydroxyalkanoates) is made through a process called bacterial fermentation. In this process, microorganisms such as bacteria produce PHA as a storage material when they are grown on renewable carbon sources like sugars or plant oils. The microorganisms convert the carbon sources into PHA, which can then be extracted and purified for various applications.
PHA has similar versatility to traditional plastics, allowing for a wide range of applications. However, what sets PHA apart is its ability to biodegrade completely, leaving no trace of harmful microplastics in the environment.
